2nd pressure switch, need to change immediately?

[CarNewbie]

Hey guys so I got the code for the pressure switch on about a week or so now. I was going to change out my 2nd transmission pressure switch this weekend when the part came in, but tomorrow I need to take a trip that is about 3-4 hours total, back and forth. Will I be okay driving tomorrow or would I really be risking something messing up?

I would change it out. Last thing you wanna do is be driving that long of a distance with a trans that won't shift correctly.
